Quite a few interesting effects. It would be nice to wipe out crazily overwhelming swarms of weak enemies with this very cool ultralaser. A bit like in Galaga Legions DX : http://www.youtube.com/watch?v=AHk-nTx14aI.

Or you may use it to blow up huge pixelated space stations. Ideally, both !

Using the same bar for life AND energy is a very good idea in my own humble opinion. You may even consider using it for the shield too. It would be very original in such a game, for what I know.

You may add a mark at a low level on your energy bar, to indicate the functioning limit for the ultralaser.

Also, allow the player to use the ultralaser at the beginning of the game, for instant gratification while playing it. And you may reward her/him by increasing the energy bar upper limit at each stage.

As for gameplay, I found that the normal bullets sprayed at the ship don't have to be avoided, because they do too little damage to the ship - the only real threats are the bullets from the bosses and colliding with the enemy. The game would pose more of a challenge if the bullets did more damage.

I tested briefly the last version on the java4k.com site. I will try it more extensively by the end of next week-end. However, I can already say that I found weird the energy bar stucked to the ship. I prefered the old version when it took almost the whole screen height. But a horizontal energy bar taking the whole screen width would be ok too.

Nice to have feedback, I'm stuck at lvl 3 in hard mode In this conditions it's really hard to evaluate all the game.Anyway, I want to thanks you all for your help, I'm pretty satisfied of my first 4k game. And I had great fun to code like that
